Surf Model Validation
Trailing 30-day mean absolute error between Tarline's Tier 2 (period-banded window model) surf height and CDIP MOP's own breaker-transformed height, per Santa Barbara beach — the acceptance target (research doc §8) is MAE ≤ 1ft for 80% of spot-days. "Observed days" counts days with at least one user-reported wave-size quick-tap feeding the bias loop.
